Jane Morgan from the Cosmos Centre at Charleville says some of its shows have already been booked out, so the influx of holiday-makers has begun.

"It brings a totally different market into play as well," she said.

"So you get the ornithologists and the birding groups that come out to have a look.

"We've had quite a number of people from Lake Eyre trips from last year that are actually coming with their vans or with their car and are going to explore more because it is, for many of them, the first time that the outback was actually exposed to them."

She says flood-ravaged towns like Roma and Mitchell are hoping for a big influx of visitors to help their struggling economies.

"They are saying, 'we are all ready' ... the bakery is back up, everyone is back up, they are ready to go and ready to look forward to welcoming people into Mitchell," she said.

"This country is looking the best it ever has and people are knowing that.

"They are seeing the images, particularly with some of the television programs flying over Lake Eyre, they can see the Channel Country in all its glory."
